The company vigorously advocates the recycling of wastewater by installing online monitoring facilities at the main wastewater discharge outlets in strict accordance with the inorganic chemical industry pollutant discharge standards and the take-over standards of the sewage treatment plant, hence the compliance rate of wastewater discharge of 100% in 2019.
Environmental-friendly lithium extraction from salt lakel
Minera Exar is a tie-up between Ganfeng Lithium and Lithium Americas Corp (LAC). Its core lithium Salt Lake project — CauchariOlaroz —is already under construction where the lithium resource reserves support an annual output of more than 40,000 tons of battery-grade lithium carbonate for 40 years. Lithium extraction from the Salt Lake takes solar energy as the main energy source and consumes very little fossil energy. The processed water used in the project takes the source that does not meet drinking-water standards, thus avoiding the consumption of fresh water. In addition, because of no need for high-temperature roasting and other links, the process effectively reduces carbon dioxide emissions. After commissioning, the Cauchari-Olaroz project is expected to become one of the most environmental-friendly lithium projects in the world.
Zero discharge of wastewater
Ganfeng Recycling's battery-grade lithium fluoride project recycles mother liquor multiple times to reduce water use and wastewater discharge. The project's water recycling rate is 82.8%.
Ganfeng Electronics and Ganfeng Battery have carried out technical transformation of wastewater treatment facilities so that the wastewater from cleaning is recycled after undergoing grilling, biochemical and sedimentation processes for equipment cleaning.
Basic Lithium Plant achieved “zero” wastewater discharge in 2021, and the learning was shared with other businesses.
Ningdu Ganfeng invested RMB 50,000 to renovate its sewage pipeline and rainwater tank pipeline based on the water quality analysis of the sewage discharged from the plant, which effectively reduces water consumption and wastewater discharge. . In December 2021, it achieved zero discharge from the sewage plant.

Efficient Use of Water Resources
In order to enhance its water management capabilities, the company has formulated a water footprint plan to increase recycling through such measures as steam condensate reuse. In addition, the Basic Lithium Plant plans to launch the construction of an ecological lake to pool the purified industrial wastewater, which will then be reused for cleaning highways, watering trees and cleaning roads in factories, thereby promoting efficient use of water resources.
Scientific treatment of wastewater
In our Mariana project, there is a sewage treatment plant on the project site to treat waste liquids and make them comply with the local waste dumping regulations, thereby preventing the pollution of groundwater in the project area.
Ganfeng Lithium organolithium plant built a new wastewater collection tank with an effective volume of 208 m3. It has effectively prevented the polluted rainwater and sewage from washing the ground from flowing into the rainwater ditch and polluting groundwater.
